Hereinafter, an operation process of the automatic battery capacity check apparatus of the wireless camera configured as described above will be described.

First, when the wireless camera 100 is installed at a desired position in order to detect a moving image using the wireless camera 100 in an unspecified multiple area for security purposes, the image detection unit 10 as shown in FIG. Detects a video and outputs image data corresponding thereto.

Then, the image digital converter 20 receives the image data output from the image detector 10, converts the image data into digital data, and outputs the converted digital data, and the controller 30 controls the image digital converter 20. The digital data outputted from the controller is input and output, and the wireless data converter 40 receives the digital data transmitted through the controller 30 and converts the digital data into wireless data.

In this case, the controller 30 receives the wireless data output from the wireless data converter 40 and outputs a control signal corresponding thereto, and the wireless short-range communication unit 50 receives the control signal output from the drive signal output unit. After receiving the input request to the wireless communication network repeater (not shown) for outputting the wireless data, and outputs the wireless data according to the IP assignment.

In this case, the wireless local area communication unit 50 may use the ultra high speed wireless LAN (Ultra High Speed Wireless LAN) currently performed on a national basis, the above-mentioned ultra high speed wireless LAN at a high speed that can transmit up to 155Mbps indoors You can do high quality video conferencing.

Meanwhile, as described above, the wireless camera 100 supplies power to the wireless camera 100 from the battery 200 so that the user can be installed at a desired position to detect an image and output wireless data. The unit 300 checks the remaining capacity of the battery 200 by checking the amount of power supplied from the battery 200 and outputs corresponding capacity check data.

Then, the power data converter 400 receives the capacity check data output from the power checker and wirelessly outputs the wireless data to the system for checking and managing the capacity of the battery 200 of the wireless camera 100. Convert to and print it out.

Subsequently, the controller 30 receives and transmits wireless data output from the power data converter 400, and the wireless short-range communication unit 50 receives a control signal output from the controller 30 to receive the wireless data.

In addition, the wireless camera 100 having a device capable of checking the capacity of the battery 200 of the wireless camera 100 using wireless data as described above may be installed in a downtown area (inside or outside of a building) or in an area without a lot of traffic. In this case, since an administrator cannot easily replace the battery 200, a solar light collecting plate (not shown), which is recently used a lot, may be installed together with one side of the wireless camera 100 or separately with the wireless camera 100. When the time to replace the 200 occurs, the control unit 30 of the wireless camera 100 automatically switches to the power charging mode to charge the battery 200 and informs the administrator of the result through wireless data. .

That is, the method of charging the battery 200 using the solar light collecting plate as described above in more detail, as described above, when the capacity of the battery 200 is discharged below a certain capacity, the wireless camera ( When the control unit 30 of the control unit 30 detects this and outputs a control signal for converting to the power charging mode, the control panel 30 receives a control signal output from the control unit 30 from a solar heat collecting plate (not shown) to supply a power supply line (not shown). While charging the battery 200 by supplying power to the battery 200, the wireless camera is installed inside and outside the building, particularly outside the city center by outputting wireless data so that the administrator can know the corresponding result. The battery 200 of 100 can be easily charged.

On the other hand, a method of automatically checking the battery capacity of the wireless camera as described in more detail as shown in Figure 2, according to the power amount check supplied from the battery 200 from the power amount check unit 300 in the control unit 30 It is determined whether the capacity check data is input (S100).

Subsequently, if the capacity check data of the battery 200 is not input in the step of determining whether to input the capacity check data (S100), the control unit 30 presets the remaining capacity of the battery 200. It is determined whether the size is greater than or equal to the capacity (S200).

At this time, the remaining capacity of the battery 200 ≥ if the remaining capacity of the battery 200 is greater than or equal to a preset capacity in the step of determining whether or not the battery 200 is set, the control unit 30 in the battery 200 The data according to the remaining capacity of the output (S300), the wireless short-range communication unit 50 receives the remaining capacity data of the battery 200 output from the control unit 30 and outputs as wireless data (S400).

Then, the operator of the management system (not shown) mentioned above can automatically check the current capacity of the battery 200 of the wireless camera 100 in accordance with the wireless data, and correspondingly installed in the wireless camera 100. The replacement time of the battery 200 may be checked.

In addition, when the remaining capacity of the battery 200 is smaller than a preset capacity in the step S200 of determining whether the battery 200 has a remaining capacity ≥battery 200, the controller 30 may determine that the battery 200 has a remaining capacity. ) And outputting the data according to the replacement (S210), the wireless short-range communication unit 50 receives the replacement data output from the battery 200 from the control unit 30 and outputs the wireless data (S220), the battery 200 Automatically notify when to replace).

As described above, the apparatus and method for automatically checking the battery capacity of the wireless camera of the present invention may automatically check the battery capacity of the wireless camera when the wireless camera detects a moving image at a fixed position or moving space and outputs the wireless data. By outputting to, the administrator can easily check the battery capacity of the wireless camera, and there is an excellent effect that the battery of the wireless camera can be easily replaced according to the checked battery capacity.
